LNB Frequency Conversion

C-band - 3.4gHz to 4.2gHz:

5,150mHz minus Tansponder or Satellite Transmitt Frequency equals the LNB IF Frequency.

E.g. Transponder or Satellite Transmitt Frequency = 3,780mHz
5,150 - 3,780 = 1,370mHz
 

Ku-band - OPTUS and PAS-2 Ku Transponder or Transmit Frequencies - 12.25 to 12.75gHz:

Transponder frequency or Satellite Transmit Frequency minus 11,300mHz equals the LNB IF Frequency.

E.g. Transponder Frequency = 12,750mHz
12,750 - 11,300 = 1,450mHz

(IF = Intermediate or "L" Band Frequency)
